Question

Решите уравнение 1 −2,6x −(0,7x + 3) = 5,7

Answer 1

Решите уравнение
1 −2,6x −(0,7x + 3) = 5,7
1-2,6х-0.7х-3=5,7
-3,3х=5,7-1+3
-3,3х=7,7
х=77/10:(-33/10)
х=77/10*(-10/33)
х=-7/3
х=-2 1/3

Answer 2

1-2,6х-(0,7х+3)=5,7
1-2,6х-0,7х-3=5,7
-2,6х-0,7х=5,7+3-1
-3,3х=7,7
х=7,7:(-3,3)
х=-7/3
х=-2 1/3

Answer 3

I can help you solve this equation. First, let's simplify the equation by removing the parentheses and combining the like terms. We get:

$$1 - 2.6x - 0.7x - 3 = 5.7$$

$$-2 - 3.3x = 5.7$$

Next, let's isolate x by adding 2 to both sides and dividing by -3.3. We get:

$$-3.3x = 7.7$$

$$x = -\frac{7.7}{3.3}$$

Therefore, the solution is:

$$x = -\frac{7.7}{3.3} \approx -2.33$$
